Battery Life
If you leave the battery charger plugged in and
constantly charging when the MWS is not in use,
the battery life is maximized for the application.
The charger will not overcharge the batteries.
The MWS has signal lights to indicate the battery
status as follows. The following voltages are
nominal (not exact) and should be used for
reference.
Flashing
Red
Warning! The batteries need immediate charging.
Voltage is below 22.5V. The station beeps continuously
to alert you of this condition. (Early models have red
lights instead of orange lights.)
Flashing Yellow Caution! The batteries are getting low. The voltage is
between 22.5V and 23.5V.
Flashing Green Go! The voltage is above 23.5V. The batteries are
charged to approximately 75% or better capacity.
The 24VDC charger has a Power LED and five Percentage LEDs. When the
charger is turned off (power LED off), the percentage LED shows battery
status. The percentage LED flashes while charging to display battery status.
When the batteries are fully charged, the 100 percent LED stays on.
If the CHARGE light does not turn on, make sure the charger is properly
connected to the batteries and the charger has AC power.
If the READY light does not turn on after 18 hours, the batteries are deeply
discharged. Call Technical Support or replace the batteries. If replacing
batteries, you must use the same type of battery from the same
manufacturer (as the ones provided with the MWS). Make sure the
batteries are NRTL-recognized. Also, BOTH batteries MUST be replaced at
the same time to maintain capacity match.
